Finally Made My First Orbit In Career Mode!

To be honest, I'm not sure where to go from here. Contracts say 'The Mun' but I'm not sure the next step.

EVA's have given me 90 Science to Spend on the 45 Point column. Any ideas on the best step in Career mode? Early Spaceplanes, or more Rocket gear?

if you want to collect science from kerbin - go planes

if you want more science - go rocket and then launch for minmus asap.

Getting to Mun is easier than Minmus, mostly because of the inclination and the size of it's SoI (Sphere of Influence). Staying and especially landing there is a lot easier with the latter though and as it's further than Mun from Kerbin you get higher science per experiment.

Personally, Minmus is overpowered regarding science and in my current game I have refused to gather any there and only going because of missions.
For a new player though, it's a gold mine and you are going to need everything you can get your hands on.

As for your next step, if you don't have it yet, aim for the Terrier. It's a must have for early game work and will enable you to get around the Kerbin system easily.
